This invention relates to glass-working machinesand has vparticular relation to the provide a simple and efiicient mechanism for applying settle-blowing ressure immediately following the intro uction of a mold charge into the mold through the funnel, by bringing a blow head into operative relation to the reviously positioned funnel and a plying hlowing ressure therethrough. 1 e application of settle-blowing ressure through the funnel reduces, by t e time otherwise required for removing the funnel, the interval of time between the mold-charging and settle-blowing operations.

A further object of the invention is to provide a blow head which alternately functions to apply settle-blowin pressure to the mold, and to provide a ba e or closure for the parison mold during the application of 'counterblowing pressure subsequent to the removal of the funnel, thereby'reducing the a number of operative parts and lessening th cost of the apparatus. 1

In the accompanying drawings:

Figure 1 isa vertical sectional viewshowing the apparatus in position for settle blowing; and v v Fig. 2 is a similar view showing the apparatus in position for 'counterblowing.

Referring to the drawings, the numeral 10 indicates an inverted arison mold having in cooperation therewith at its neck porp tion a neckring 11 and a neck plunger 12 for forming the finish on the ware. The mold 10 may be mounted on a rotary mold-table, ormay be disposed at a fixed station, asin the individual-section machine shown inmy copending' application for Letters Patent, filed August 30, 1924, Serial No. 735,079. The neck plun er 12 is positioned within a head 13 throu h which counterblowing pres sure is applie the plunger being arranged for vertical movement in the usual manner.

The mold 10 has a cavity 14 which is open to the atmosphere at the to to receive a mold charge 15 which is de ivered thereto from a deflector 16 cooperating with the chute of a glass feedin machine, not shown.-

For the purpose 0 guiding the mold charge 15 ,into the-mold cavity 14, a funnel 1-7 is loosely mounted on one end of an arm' I '18 so as to permit a suflicient'amount of floating movement to insure roper horizontal positioning thereof wit respect to secured to a rod 19 which-is oscillatedhorizontally to move the funnel to and from ia the mold. The other end of the ar'ni*18 is position in vertical alignment with the mold .10. Verticalmotion is also imparted to the rod 19, in order toraise and lower the-fun v nel\ 17 out of andinto aoperativefposition with respectto the'mold10.'

The blow head 24 is resiliently secured to.

the head 25 to allow a limited amount of horizontal floating movement in order, to

insure an accurate re 'str and an'air-tight fit between the blow i and between the blow head and the funnel 1 7 when the blow head is moved into operative position with either of these elements. This is accomplished by providing in the top of the blow head 24 a stud 29 which ea and the mold 10 recess 33 formed in the up extends loose] through an aperture formed in the cured to the upper extremity of the stud 29 and bears upon a coiled spring'32 which sur- 1 rounds the stud 29 and which is seated ina r surface of the head 25. The'blow' hea 24 is prevented ,from rotating with respect to the head 25 by a' horizontal rod 34 which is secured at one end to the blow head and which passes between two ins 35 carried by the arm 26,. only one oft shown onthe .Settle-blowing pressure is conducted to the interior of the'mold. 10 through a lu- 'rality of assages 36 provided in the b ow ese 'passa es communicate with an. annular passa e3 which is provided 'in 'the" lower sur ace of the head 25 and which communicates with a passage 38 in the arm 26. The passage 38' communicates with a passage 39' provi a port 40. .The passages 36 are so positioned that they communicate with the interior of the funnel 17 'when'a plying settle blowing ressure toxthe mol but when the blow ead 24 is lowered to-provide a closure for the mold during the counterblowing .opera- .tion, the passages 36 are closed by the u per surface of the recess 22 in said mol as shown in Fig. 2-. j I

A recess or de remon. 41 is formed in the i bottom or the b ow head 24 and is adapted l is then lowered and correctl registry with the funnel, (Fig. 1) clamp ng to register with the mold cavity 14 to provide a bottom mold for the parison of the proper shape.

In operation, the funnel is swung over and down to a proper seating contact with the mold prior to t delivery of a mold charge. After the charge has entered the mold the blow head is immediately swun into alignment with both the funnel and e mold, and positioned in the latter firmly in position. Settle-blown pressure is then admitted; to the mol throu h the several ports and passages of Fig. 2), and is so placed'that the bottom the b ow. head structure to pack the glass around the neck plun The blow head is then raised to a osition which willallow the funnel to be -li ted and swungaside b the funnel arm, and the neck plunger is wit drawndownward in the usual manner.
